` To all wh om t may concern Be it known that I, HENRY L. REYNOLDS, a citizen of the United States, and resident of the city of Seattle, King county, Washington, have invented certain new and useful Improvement-s in Cream-Removers for Milk- Bott-les, of which the following is a specification. A

My invention relates to cream removers for bottled milk, and comprises a novel construction for removing the cream from the type of bottle which is very generally used for delivering milk, whereby the cream may l' be removed without, at the same time, gettinga large percentage of milk.

The object of my invention is to make possible the removal of the' cream from such bottles without -having .to dilute it with milk. The scope of my invention and of what it consists, will be seen from a study of the following specification, andthe same will be particularly dclined in the claims which terminate the specification.

In the accompanying drawings I have shown a number of modified constructions which embody my invention, thef'same containing the constructions which are now pre -ferred by me. i i

Figure l is a sectional elevation of a bottle and my device in place thereon. Fig. 2 is a plan view of the cap which is applied to the bottle. Fig. 3 is a front elevation of this cap or spout member of my device. in the same construction as is shown in Figs. l and 2. Fig. 4 is a sectional elevation of a modified form applied to a bottle. Fig. 5 is a plan viewof the form of device shown irri Fig. 4. Fig. G` is a sectional elevation of another :torni of construction shown in place on a bottle. Fig. 7 is a sectional elevation of another type of construction shown in place on a bottle. Fig. 8 is an elevation of the same, not in section. Fig. 9 is a sectional elevation of a modified form upon a' bottle. Figs. l0 and 11are sectional eleva# tions of modified constructions shown upon a bottle.

The type of hott-le with which I have shown myt invention, is that type which has come into almost universal use for the deliveryofmilk bottles, and this includes a very large percentage of all the milk which is delivered to the family trade. Such bottled milk, either due to the length of time since it was bottled, or to the treatment given' the product before bottling, at xthe time of receipt by the consumer has a considerable accumulation of .cream at-the top, and it is often desired that this cream, or some part of it, be removable without 'diluting it'with milk. To pour the cream from s uch a bottle without pouring oil a considerable amount'of milk, is impossible. By the use of my device. it is possi-ble to remove all, or as much as may be desired, of the cream withoutdrawing with it any of the milk. f

or pouring member, which fits the topof vthe bottle, and a displacement plunger which will pass through said. cap into the bottle. The cap should be so constructed that it will be possible to make-a tight connection be` tween it and the bottle, thereby preventing leakage of the cream between, and it should also'have al depressed portion or spout at one side, through which the cream will be delivered in' a single stream, where it may be caught' in a receptacle provided for it.

The form n of cap` 'orspout member, as

'fshownin Figs; 1,:,2 and 3, has a neck l, de-

signed for ftting'within the bottle neck and to make a tight joint therewith, without using a packing'ring. To enable-this neck to spring, as may be necessary to tightly fit necks which are not truly circular, it is desir-able that the neck l be made of thinand springy metal. It is also desirable that this neck l be slightly coned, to thereby tit the bottle necks, if they vary somewhat in exactness of dimension. Secured to and formin'g a continuation of this neck l, is a wall 2 ,whichextends to -a short distance above the top of the bottle. At one side this wall is bent down to form a spout, from which the cream willflow. The'metal at this point may be extended farther thanwould be due to the height of the wall 2, if it is desired to have a longer spout. This is however, not essential. `It is desirable that this spout be slightly inclined downward.

The type of construction shown in Figs. 4 and 5, diiers from the above only in having the upwardly extending restraining wall curved'xbackward toward the center. in its upper portion. I have, however, shown Aa packing ring 7 as placed about the upper part or base of the cone formed by the neck 1, where it enters the recess in the' bottle4 mouth 'n which'the paper disk is placed My device is composed of two parts, a cap when sealing the bottle. This expedient may be employed when desired and if. found that thecap'. d oes not make :1r-sufficiently tight joint with the bottle neck.vr

In Fig. 6 is shown a type of construction in Vwhich the restraining wall is' like that shown in Fig. 1, but in which the neck 1 is` replaced by a short neck 8, which terminates at its lower edge in a slight outward flange- 9, a packing ring 7, of rubber, being placed in the groove thus ormed.- This'- plan of* making a tight joint with the bottle may be applied to any and'all the types shown'in the preceding figures.

In Figs. 7 toll, inclusive, I have shown modifications in which 'the sealing 'contact between the bottle and the cap'is upon .the

exterior surface of the bottle. In the form shown in Figs. 7 and 8, the apron which extends downward over the bottle head is slit and designed to grip the head of the bottle and, by the spring action of the tongues 10hold the cap securely in. place.

This has a rubber ring 7 seating just'under the shoulder'll, whereby a tight joint is secured.

In the type shown irFig. 9 the body vthereof is large enough' at its lower side,

to pass over the bottle head and'hasa rubber ring 73, of a type resembling the rubber ring used for sealingthe type of'i fruit jar which -is commonly known as the Mason jar, secured by its outer edge' in a seam crimped in the edge of the metal of which the cap is formed. This construetion is capable'of fitting tightly upon bottles of considerable variation in size. Thetype shown .in Fig. 10 is like tha shown in Fig. 7, except that the apron is not slit into the tongues 10.- The type shown in Fig. 11 resembles that shown ih Fig. 9,- except that the ring of rubber is more like a section of a tube and is cemented or placed within the tapering apron'lL The displacement plunger which is to be used with each and all these types, may be constructed of any material found suitable. for the purpose, although some materials and methods of construction will be .found more desirable than others. The plunger 4 as shown, is intended to be made of metal, as a tube with its ends closed, or at least, one end closed. While this might be provided with one-or more longitudinal grooves for the upward flow of the cream, I believe it to be, on the whole, more desirable to. make it of true circular cross section, a little less in diameter than the hole in' the cap.A

Aso

The length of this plunger should be such as will either remove-all the cream, or extend intocontact with the bottom of the bottle. As its vouter surfacogs smooth and free of all seams, itmay easily be cleaned perlectiv and kept in absolutely sanitary condition. Among the materials'which are 65 well adapted'for making this plunger are, seamlessf metal tubing, preferably of aluminum orof other metal plated with nickel, 'a-seamed metalztubewith endsclosed and thencoated with. a tire-baked enamel, such "for lnsta'nce, asis use" in making what is known as granite ware;' or it may be made of glass tubing or solidjglass, or'

earthen Vware glazed.

AIn using my.device, the capis placed upon the .bottle andv pressed down so as to secure as tight ajoint as necessary, ajreceptacle placed -to .receive the discharged cream and the plunger inserted and ressed slowlydoiifnward. As the cream is ighter than themilk andthe insertion of the plunger does not stir up the contents of the bottle, the cream will- How out-before the milk will come. As the plunger is insertedin the bottle the contents thereof are forced out, in an amount equal in volume t0 the volume of the plunger inserted in the bottle. l

Both parts ofthis devicel are ofa construction and :material which may be thor- 4oughly and easily cleansed and kept in sani- 90 ltary condition. vAll surfaces' areexposed and accessible for cleaning. v r

The "cap may be made of. thin metal, for which I-prefer` aluminumor, if m'ade of ironor brass, that it be nickel plated. It is '95 desirable` that the neck l which enters the bottle, be 'of such thinness and resiliency, .thatl itcwill spring under slight force, to conform 'to the inequalities of surface of the bottle mouth, thereby making a tight joint. l

While a 'tight joint may be secured by the use of a'ring of rubber orothercompressible materia-l, I prefer to secure this, if a possible, without. using anything of this Y sort, as the device'in'ay'be thus kept in more -105 sanitary condition.

A material which might beused .to advantagegfomaking'both parts' of this device,f isifxno'ldedv paper, preferably waterproofe'd in some manner. Such' contruc- 110 tion would be of a; more temporary character and much less desirablefrom the standpointof 'sanitation andv durability, -but otherwise it 'would be` a very desirable material. They might also ber made of cellu- 115 loidor any other-'material 'which may be cheaply formed into the desired shape and Vwhich-is not objectionable from a sanitary standpoint. Glass might be used to advantagein making the cap, for such constructions as engage the outer surface of the bottle, provided a packing ring, may be em- 'ployed for securing a tight joint.V It would not be desirable for making the types which engage the inner surface of the bottle mouth, for the reason that their necessary thickness would consume too much of the space and forbid use of a. plunger as large as is desirable. My invention, however,

does not lie in the use of any special material.l
